Drive modes are nothing new, but BMW may go for more detailed customization in future performance EVs., a recent patent application filed with the United States Patent and Trademark Office goes beyond current drive modes, allowing drivers to tailor things like throttle mapping and torque delivery to dramatically change the behavior of a car.
Instead of a limited number of modes like Sport and Eco with fixed settings, this system would give drivers a graph from which they could choose custom settings, according to the application. It takes advantage of the greater flexibility of electric motors, which can be powered up or down in a linear fashion, like a dimmer switch.
